Abstract
PURPOSE: To prevent a surge applied to a primary side amplifier due to the spark discharge current in a secondary coil, by means of connecting a shielding substance, which is provided between the secondary coil and the primary coil, to the ground together with one end of the secondary coil.
CONSTITUTION: In the periphery of a core 1 is provided a secondary coil 3, and around its peripery is rolled on a shielding substance 5 made of craft paper and copper foils, further to its periphery is concentrically installed a primary coil 8. And a lead wire 21 of the shielding substance 5 is connected to an earth terminal 16 together with a winding end of the secondary coil 3. Consequently, with a current continuously flowing in the primary coil 8 through a transistor 26 of the amplifier 25, when a spark discharge current flows in the secondary coil 3, no spark discharge current flows in the primary coil 8 also with a surge not applied through a stray capacity, thus capable of operating the protection of the amplifier 25 without using a condenser.
